Hammerspoon configuration
My hammerspoon configuration. Feel free to borrow/steal.
mover
The mover module is a lightweight copy of an old OS X program I used
called MercuryMover, now sadly
defunct.
Hitting Function-Command-Up (Command-Pageup on a full-width keyboard) starts the movement mode, where up/down/left/right will move the active window about in 10 pixel increments. Hold Shift to move by 1 pixel, Option to move by 100 pixels, and Command to move to the screen edge. The Equals key will center the window, and Plus (Shift-Equals) will resize the window to the size of the screen.
Hitting Function-Command-Right (Command-End) starts the resize to the right mode, where up/down/left/right will resize the window from the bottom/right edges.
Hitting Function-Command-Left (Command-Home) starts the resize to the left mode, where up/down/left/right will resize the window from the top/left edges.
init.lua
As each computer I use this on may have subtly different mover
requirements, I create init.lua as a symlink to the right
$HOSTNAME.lua file on installation.
